Whether a man is bound to restore whatever profits he has made out of money gotten by usury?

❌ Objection 1 : It would seem that a man is bound to restore whatever profits he has made out of money gotten by usury. For the Apostle says (Rm. 11:16): "If the root be holy, so are the branches." Therefore likewise if the root be rotten so are the branches. But the root was infected with usury. Therefore whatever profit is made therefrom is infected with usury. Therefore he is bound to restore it.

❌ Objection 2 : Further, it is laid down (Extra, De Usuris, in the Decretal: 'Cum tu sicut asseris'): "Property accruing from usury must be sold, and the price repaid to the persons from whom the usury was extorted." Therefore, likewise, whatever else is acquired from usurious money must be restored.

❌ Objection 3 : Further, that which a man buys with the proceeds of usury is due to him by reason of the money he paid for it. Therefore he has no more right to the thing purchased than to the money he paid. But he was bound to restore the money gained through usury. Therefore he is also bound to restore what he acquired with it.
